    The test to kill all three variables in one step is the F test with test stat 12.82165585 and you compare it to an F_{3,36}.
    The p-value is P(F_{3,36}>12.82165585) and the printout gives that value as 7.48476E-06.
    So as long as \alpha>7.48476E-06, you reject H_0 which is that all three variables can be dropped.
    But with such a small p-value the conclusion is that we do indeed need at least one of those three terms to explain these people's salary.
